NAME

       explain_putw_or_die - output a word (int) and report errors

SYNOPSIS

       #include <libexplain/putw.h>
       void explain_putw_or_die(int value, FILE *fp);
       int explain_putw_on_error(int value, FILE *fp);

DESCRIPTION

       The  explain_putw_or_die function is used to call the putw(3) system call. On failure an explanation will
       be printed to stderr, obtained from the explain_putw(3) function, and  then  the  process  terminates  by
       calling exit(EXIT_FAILURE).

       The  explain_putw_on_error  function  is  used to call the putw(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_putw(3) function, but still returns to the caller.

       value   The value, exactly as to be passed to the putw(3) system call.

       fp      The fp, exactly as to be passed to the putw(3) system call.

RETURN VALUE

       The explain_putw_or_die function only returns on success, see putw(3) for more information.  On  failure,
       prints an explanation and exits, it does not return.

       The explain_putw_on_error function always returns the value return by the wrapped putw(3) system call.

EXAMPLE

       The explain_putw_or_die function is intended to be used in a fashion similar to the following example:
              explain_putw_or_die(value, fp);
